  during

  and 
  young 
  fish 
  continue 
  to 
  remain 
  upon 
  thf 
  grounds, 
  and 
  in 
  all 
  

   other 
  places 
  where 
  the

  be 
  unduly 
  harmful. 
  

  

  Naked 
  hooks 
  for 
  stiirrjeon. 
  — 
  It 
  is 
  recommended 
  that 
  the 
  method 
  of 
  taking 
  sturgeon

   for 
  its 
  capture, 
  accompanied 
  by 
  extensive 
  fish-cultural 
  operations, 
  may 
  be 
  expected 
  

   to 
  :iid 
  materially 
  in 
  rejilenishing 
  the 
  stock; 
  but 
  we 
  venture 
  to 
  suggest 
  that, 
  in 
  

   our 
  oijiniou, 
  even 
  greatei 
  benefits 
  might 
  be 
  gained 
  by 
  the 
  discontinuance 
  of 
  all 
  

   fishing 
  for 
  the 
  species 
  during 
  all 
  or 
  a

  elsewhere 
  

   explained.

  be
